Percent Composition By Mass Part 2

Percent composition by mass always follows the same three steps. In this example, you will understand how to calculate the percent composition of each element within a compound that has a polyatomic ion specifically the compound of calcium nitrate. This Chemistry tutorial will help you identify how many of each element there is in a compound with multiple subscripts.

📚 I made the mistake of buying all of my textbooks, I wish I had the option of renting them. Thankfully you do, with Chegg Textbook Rentals.

💁‍♀️ HI I'M MELISSA MARIBEL
I help students pass Chemistry and Organic Chemistry. I used to struggle with this subject, so when I finally graduated with a bachelor's degree in Chemistry, I became a tutor so that you wouldn't have to struggle like I did. I know that with the right help, YOU CAN LEARN ANYTHING!

Can we find mass by percent composition?

[borntotumbleedits]

What if you are given the percent composition of an element in an unknown substance, and you need to calculate how many grams that element is?

[lazychief]

OMG that was literally the question I had on my test, I totally understand now 👍
